Fig. 1 shows the structural representation of the blower fan screen net cleaning control device according to a kind of mode of execution of the present utility model.As shown in Figure 1, blower fan screen net cleaning control device 100 of the present utility model comprises controller 110 and ultrasonic generator 120.
Wherein, controller 110 can comprise ultrasonic wave controller 111 and controller of fan 112.Ultrasonic wave controller 111 is electrically connected with ultrasonic generator 120, control the startup of ultrasonic generator 120, ultrasonic generator 120 sends ultrasound after starting, this ultrasound is delivered on the filter screen of blower fan 130, cause filter screen dither, thus the dust on filter screen and/or foreign matter are shaken.
Controller of fan 112 is electrically connected with blower fan 130.While ultrasonic generator 120 starts or when ultrasonic generator 120 starts after a while, controller of fan 112 controls blower fan 130 by the sometimes fast and sometimes slow rotation of predetermined period, control the sense of rotation of blower fan 130 simultaneously, change into outdoor air draft by indoor air-supply, thus filter screen will shake the dust that gets off and/or foreign matter blows to outdoor.Controller of fan 112 controls blower fan 130 and rotates sometimes fast and sometimes slowly, thus can utilize anxious to stop, anxious acceleration and the dust in blower fan fan page is shaken off.
The cleaning being ultrasonic wave controller 111 and controller of fan 112 and controlling the filter screen to blower fan 130 in automatic mode described above.In automatic mode, ultrasonic wave controller 111 and controller of fan 112 are automatically the filter screen dedusting on blower fan according to the time of presetting.Alternatively, ultrasonic wave controller 111 and controller of fan 112 also can control the cleaning of the filter screen to blower fan 130 in a manual mode.In a manual mode, ultrasonic wave controller 111 and controller of fan 112 can be selected to be the filter screen dedusting on blower fan at any time as required.
In addition, blower fan screen net cleaning control device of the present utility model can also comprise mode converter (not shown), and this mode converter is suitable for control mode to change between automatic mode and hand-held block.When mode converter is switched to manual mode by staff when, blower fan screen net cleaning control device of the present utility model starts immediately, starts according to described mode above the filter screen cleaning blower fan 130.
When mode converter is switched to automatic mode by staff when, described controller or ultrasonic wave controller send actuating signal according to first scheduled time to ultrasonic generator, produce ultrasound to make ultrasonic generator.Described controller or controller of fan transmitted control signal to described blower fan according to second scheduled time, controlled described blower fan and rotated according to predetermined period and change into outdoor air draft by indoor air-supply.Wherein said first Preset Time and described second Preset Time are synchronous, or described first Preset Time is slightly early than described second Preset Time.
Fig. 2 shows the schematic diagram of the blower fan be provided with according to blower fan screen net cleaning control device of the present utility model.As shown in Figure 2, blower fan 130 is with fan 132, and one end of blower fan 130 is fixed on the bottom position of electric equipment chamber near the wall 10 of outdoor side.Blower fan 130 is placed in a framework 20 usually; near fan side, filter screen 131 is being installed; thus when blower fan 130 is worked; both can play the effect made outside the heat discharge chamber of electric equipment chamber indoor, can prevent again dust or foreign matter from entering blower fan 130 and affecting its working effect or performance.Ultrasonic generator 120 is fixed on the side of the close fan of blower fan 130.Controller 110 (not shown in fig. 2) is arranged on the wall of fixing blower fan, such as the position on fixing about 1.8 meters, the ground of distance on the wall.Be connected by wire between controller 110 with ultrasonic generator 120, the 3 core copper cables of 1.0 square millimeters are such as used to connect, controller with and blower fan between be also connected by wire, such as connected by the 4 core copper cables of 2.5 square millimeters, the part that these wires are positioned at metope can be arranged in vinyl tube within the walls along wall.
Below by an example, blower fan screen net cleaning control device of the present utility model is described.
When the mode of operation of blower fan screen net cleaning control device 100 is arranged on automatic mode by staff, here, set blower fan 130 often work two weeks time blower fan screen net cleaning control device 100 pairs of blower fans 130 filter screen 131 clean once.When blower fan 130 has worked two weeks, (namely blower fan screen net cleaning control device 100 starts automatically starts working, described first Preset Time and described second Preset Time are two weeks), wherein ultrasonic wave controller 111 starts ultrasonic generator 120 automatically, ultrasonic generator 120 sends ultrasound and propagates in atmosphere, when it is delivered on filter screen 131, the high-frequency vibration of filter screen 131 can be caused, thus the dust on filter screen 131 and/or foreign matter are shaken.While ultrasonic generator 120 is activated, controller of fan 112 sends control signal to blower fan 130, make blower fan 130 according to predetermined period sometimes fast and sometimes slow rotate, this predetermined period is set as 15 seconds, rotate with rated speed at 5 seconds blower fans 130, reduce speed now second at 6-10, start to accelerate to rated speed second at 11-15, the acceleration utilizing blower fan sometimes fast and sometimes slow can be shaken off the dust that the fan fan page of blower fan is adhered to.The sense of rotation that the control signal that controller of fan 112 sends simultaneously also controls blower fan 130 changes, and changes into outdoor air draft, thus the dust that filter screen 131 falls and/or foreign matter are blown to outdoor by indoor air-supply.
Utilize blower fan screen net cleaning control device of the present utility model, can by ultrasound, control rotation speed of fan and turning to and effectively remove dust on filter screen and/or foreign matter, ensure the exhaust effect of blower fan, and then ensure the safe operation of the indoor electrical equipment of electrical equipment thus extend its working life.
